Does Playing Video Games Really Make Cognition 13.7 Years Younger? An Interpretation of a University of Western Ontario Study
Adults who frequently play video games score, on average, as if they were 13.7 years younger on cognitive tests, but this is only a correlation, not causation. The following article breaks down the study design, possible explanations, the game economy background, and the diagnostic criteria for "gaming disorder."
How the Study Was Conducted
The study was completed by a team at the University of Western Ontario in Canada and published in PLOS One on October 24, 2025. The paper's topic is the benefits of exercise and video games for cognition and mental health. Ultimately, 923 adults were included in the analysis, and participants completed 12 cognitive tasks.
Sample and Methods
The study initially had 2,627 people sign up. After screening for data completeness and outliers, 923 remained for analysis. Participants self-reported their exercise and gaming habits, then completed 12 tests covering dimensions such as short-term memory, reasoning, language ability, and processing speed.
Core Results
Participants who spent more time gaming each week generally performed better on indicators such as short-term memory, language ability, and reasoning. The researchers converted the difference into a "cognitive age": high-frequency gamers were about 13.7 years younger than non-players.
According to the researchers' statement, low-frequency players who played less than 5 hours per week were also about 5.2 years younger than non-players.
Why "Active Engagement" May Be Key
Active decision-making activities are more likely to engage cognitive resources than passively receiving information. This is an explanatory hypothesis for the results, not a conclusion directly verified by the study.
When passively scrolling short videos, users hardly need to make decisions or plan. Games (especially FPS and strategy games) require players to complete observation, memory retrieval, tactical judgment, and operation within extremely short periods of time.
According to a retelling of the paper, heavy strategy games and FPS games had the strongest association with cognition, while pure idle mini-games showed almost no improvement. This detail should be verified by readers against the original paper.
